Career:
Ehsan Samei, PhD, DABR, completed his PhD in Nuclear Science, and MEng in Radiological Health Engineering from the University of Michigan in Ann Arbor prior to his MS in Medical Physics from Georgia Institute of Technology. Following his formal education, he served as an Adjunct Research Investigator at the University of Michigan in Ann Arbor, as a Medical Physics Fellow at Henry Ford Hospital in Detroit, and as an Assistant Professor of Radiology and the Technical Director of Radiology Informatics at the Medical University of South Carolina in Charleston. He is currently a tenured Professor at Duke University with faculty appointments in Radiology, Medical Physics, Biomedical Engineering, and Physics. He is involved with medical physics research, education, and clinical service. At Duke he serves as the Director of Carl E. Ravin Advanced Imaging Laboratories (RAI Labs), the Chief of Clinical Imaging Physics Group, and the Director of Graduate Studies for the Medical Physics Graduate Program, of which he was a co-founder. His current research interests include quantitative imaging, molecular x-ray imaging, and theoretical and experimental methods in medical image formation, analysis, display, and perception. He has been the recipient of multiple grants from national agencies, has over 200 publications (as of 2009), and is a frequent invited speaker at national and international meetings. He has further held leadership positions in a number of professional organizations, including AAPM and RSNA. He has served and continues to serve on many AAPM task groups including chairing the AAPM TG18, which developed the first national guidelines for medical displays. He has further served as the Scientific Program Co-director of the AAPM national meetings in 2003 and 2004, the vice-chair of the AAPM Imaging Physics Committee (2005 – 2007), and the Symposium co-director of the SEAAPM in 2007. He currently serves on the AAPM Science Council, is the Chair of the SPIE Physics of Medical Imaging Conference, and is an Associate Editor of Medical Physics. He is also currently the President-Elect of the Southeast Chapter of the AAPM. Sponsored by the AAPM, in 2008, he was a co-founder of the new Society of Directors of Academic Medical Physics Programs (SDAMPP), to promote advancement of medial physics education and coordination among medical physics educators.
